ES256602U - Automatic lock cursor for zip closures (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Automatic locking slide for zip fasteners, having a pair of rows of coupling elements, comprising a cursor body including a pair of first and second fins joined at a first end by a neck in order to define a channel of Y-shaped guide between the fins for the passage of the pair of rows of coupling elements of the slide fastener, the first fin having an opening communicating with the guide channel; a pair of ears spaced laterally on the first fin, one on each side of the opening; a locking element made of a piece of elastic strip and pivotally supported on the body of the slider, the blocking element having a locking prong for projecting guide channel generally through the opening to engage the pair of rows of elements of coupling and blocking them; and a pull tab pivotally attached to the ears and provided with a cross member rotatably mounted thereon, the pull tab being operatively attached to the locking element to retract the locking prong of the guide channel in the opening; characterized in that: said neck (13) has a nose (23) for retaining locking element next to said second wing (12) "; and in that said blocking element (24) further has a U-shaped base (25) that extends around said crosspiece (18) and is normally forced against it by the elasticity of said strip (24), said base (25) of angular movement outside said first fin (11) in response to pivoting movement of said pull tab (17) against the force of the strip (24), and an anchor (26) extending from a first end of said base (25) and ending in a hook-shaped end (27) engaged with said holding nose (23), said hook-like end (27) being normally forced against said nose (23) by the elasticity of said strip (24) and thus prevented from disengaging from said nose (23).
